4 Claims.

' My invention comprises a detachable aspirator and more specifically, a device for use in connection with a resuscitator inhalator machine. Resuscitator inhalator machines are well known in the art, but in'emergency uses often a patients throat and air passages are plugged so that the resuscitator or inhalator cannot administer oxygen to the patients lungs and it is therefore necessary to use an aspirator to draw ofi the congesting matter.

it has been found in the use of aspirators that they often become plugged by the matter being aspirated. As it is often a matter of seconds to save the life of a patient, it is necessary that the aspirator be cleanable in a matter of a few seconds so that "it can be put back to use on the same patient.

It is therefore the purpose of my invention to provide a detachable aspirator which can be applied to the usual resuscitator machine to remove the congesting matter in a patients throat.

Another object of my invention is to provide a detachable aspirator which can be cleaned in a matter of seconds.

Other objects and advantages of my invention will be apparent from the following description of the preferred embodiments.

In the drawings:

Figure 1 is an elevational view of my detachable aspirator.

Figure 2 is an enlarged elevational view thereof.

Figure 3 is a sectional View taken on the line 3--3 of Figure 2.

A detachable aspirator constructed in accordance with my invention is adapted to be used in connection with a catheter I attached to aflexible tube 2, a settling bottle 3 and a flexible tube 4, and a resuscitator inhalator 5. A resuscitator is used for artificial respiration when the breathing of a person has ceased and the inhalator is used to supply oxygen to a patient who is breathing.

The ordinary resuscitator inhalator has a nipple 6 threaded to it to permit a blast of oxygen to be emitted. Over this nipple 6 I apply my detachable aspirator. This aspirator has a body member I having a bore 8 continuously therethrough and the inner walls of the body I are threaded as shown at 9.

Extending laterally from the body I is a nipple l having a bore H connecting with the bore 8. Flanges l2 on the nipple l0 provide a means for holding the flexible tube t thereon in a sealing condition so that oxygen can pass through the bores 8, II and the tube 4 to the settling jar that are too light to settle in the settling jar 3 'will pass into the Venturi tube and-plug up the throat or lungs.

2 3, from the settling jar 3 to the flexible tube 2 to the catheter Threaded into the body 1 is a Venturi jet l3 which is directed to pass thefloW of oxygen out of its end l4 into the Venturi tube I5 threaded into the bore 8.

A boss I6 is threadably attached to the column I! of the resuscitator inhalator 5 and has a passage 2! connecting the interior of the resuscitator column I! and the Venturi tube IS.

A rubber washer I8 is ordinarily supplied upon the resuscitator inhalator surrounding the nipple 6. The body I passes over the end of the nipple 6 and engages the rubber washer. 18 to make an air-tight seal. The body I is held in position against the rubber washer l8 by a tube I9 engaging the tapered shoulder 20 of the Venturi tube l5 and held in position in the passage 2| in the boss l6.

In the operation of my device, when it is desired to aspirate a patients lungs, the catheter l is placed in the throat of the patient and oxygen blown from the resuscitator inhalator through the nipple 6, through the Venturi jet 03 into the Venturi tube I5, through the tube I9, passage 2! and into the column I! where it is disbursed to the atmosphere. The passage of oxygen through this system will suck material through the nipple Hi, the flexible tubes 2 and settling jar 3 and catheter I from the patients However, any solid materials will settle in the settling jar 3, but often the settling jar 3 will fill and then material will be drawn into the Venturi tube. Also small particles Venturi tube l5. As the operator of my aspirator often has a matter of seconds to work upon a patient, if the aspirator becomes plugged it must be cleaned immediately. To do this the boss I6 is rotated on its threads by pressing upon the extension 23 of the plunger 22. When this is done the entire aspirator is snapped off from the nipple 6 and can be immediately cleaned by holding the opposite end against the jet of air from the nipple 6, or cleaned in any other manner, and snapped back into position, restoring the boss It to its original position. However, if there is an obstruction in the tube 4, or catheter I, the catheter must be quickly withdrawn from the patients throat and by moving the extension 23 upwardly in the boss IS the plunger 22 will close the end of the tube l9, blocking the flow of oxygen through the Venturi tube l5 and forcing same out through the nipple ID, the flexible tubes, etc., and blast any material lodged in the 3 line out through the catheter. Release of the plunger 22 will immediately restore the proper circulation and permit the catheter to be reinserted and the aspirator returned to its normal operation.

While I have described the preferred embodiments of my invention, I do not wish to be limited to any of the details herein set forth, but my invention is of the full scope of the appended claims.

I claim:

1. A detachable aspirator adapted. to. be. attached to a device for supplying oxygen, said' oxygen supplying device having a supporting column and a nipple adjacent said supporting column, through which nipple oxygen is ported from said oxygen supplying device, comprising: a body having an opening for the reception of the nipple on said oxygen supplying device and.

a sealing member to seal said body against said oxygen supplying device, a Venturi jet threadablymounted therein, a Venturi tube threadably mounted.- in said body and a nipple adjacent said jet, 2. boss, attachable to the supporting column of said oxygen supplying device and rotatable thereon, means for porting the discharge from said Venturi tube through said boss into said column; said means comprising a passage through said boss, and a tube inserted in said passage and. engaging said Venturi tube, said boss holding said tube against theend. of said Venturi tube andsaid body against said sealing member.

2. A detachable aspirator adapted to be attached to a device for supplying oxygen, said oxygen supplying device having a supporting column and a nipple adjacent said supporting column, through which nipple oxygen is ported from said oxygen supplying device, comprising: a" body having an opening for the reception of the; nipple on said oxygen supplying device and a" sealing member to seal said body against said oxygen supplying device, a Venturi jet threadably mounted therein, a Venturi tube threadably mounted in said body and a nipple adjacent said jet, a boss attachable to the supporting columnof said oxygen supplying device and rotatable thereon, means for porting the discharge from said Venturi tube through said boss into said column, said means comprising a passage through said boss, a tube inserted in said pas.- sage and engaging said Venturitube, said boss holding said tube against the end of said Venturi tube and said body against said sealing member, and a plunger adapted to move in said body to seal said tube.
